T0 01 whom it "may 'co /w'er'n:

Be it known that I, LOUIS ZSIKI,"CltlZ6I1 ofHu'ngary, res ding 'at VV'harton, in the county of 'Morris and Stataof l\ ew'-.-lei'scy, have-invented certainnewfiand useful Improvements in'Sl Propulsion 'andGontrol Means,of which tnefollowing is a specification. I I i This invention relates to "ship propulsion mean'sin which suitably driven prop'ellers have -the'water iconducted thereupon through conduits arranged fhr'conti olpf the-fiowiof water therethroughythe invention having for an objectrthei'provisionof a novel ship propulsion means of tlris"soi't,-a further spe cific object "relating to the provisioniof valve means for controlling a pair ojfficonduits.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is a plan view of a ship having the invention applied thereto.

Fig. 2 is a fragmentary transverse sectional view showing the means for controlling the water conduits, this view being taken on the line 22 of Fig. 3.

Fig. 3 is a plan view of the said means.

Fig. 4 is a fragmentary longitudinal section on the line 4 -4 of Fig. 1,

In the drawing the reference numeral 10 indicates the hull of a ship. Extending longitudinally through this hull are. a pair of tubes, forming water conduits, and which are located one on each side of the ship below the water line. In these tubes are placed propellers, which are driven from a motor or engine 15 through the medium of the bevel gear 16. on the engine shaft that engages with a bevel gear 17 on a trans verse shaft 18 to the ends of which are fixed ordinary paddle wheels 18 enclosed in housings such as 19 and intersecting the conduits on their lower sides. The conduits 11 are adapted to be controlled by suitable valve means whereby thewater may be directed as desired therethrough. Each conduit is controlled by a valve plate 22 slidable thereacross in suitable guide elements 23, each of these valve plateshaving a projecting stem 24, these stems overlapping one another and being formed with rack teeth 25 on their adjacent"facesthatmesh with a spur gear 26 fiX-cd'ona stiib shaft :27 on which is also aFWOrnigeai-QS engaged by'a worm pinion 29 011 the shaft of an electric motor 30. l The shaft- 27 is supported'by a bearing element 32 on fa "base plate or member 34 that "is adj ustable transversely of "the ship, the motor BOJbei-ng also 'mo'unted'on this ."plate 34, so as to be adjustable "therewith. This plate 34'1nay'be guided by suitable means suchas the pins fiz'zedto a flooring element 36011 which th'e'plate rests and engaging inslots 37 in the plate. To adjust the plate 34 transversely of the ship, a shaft8'9 is fiXed at oppositefends to projections 3'4 from the plate 34 and is formed -with screw threads 40that are engagedby the threaded'boreof a bevel gear 41 loose on the shaft, this gear being retained against movement transversely of the ship by means of the bearing elements 42 fixed on the floor-36. The gear 41 is engaged by a bevel pinion 43 on the shaft of a second electric motor 44, this motor'being mounted on the flooring 36.

As will be apparent, by causing the motor 30 to operate, the flow of water through the other devices as may be desired.

Having thus described my invention, what I claim as new and desire to protect by Letters Patentof the United States is as follows:

1. In a ship, a pair of water conduits extendinglongitudinally through the ship,

propeller wheels in said conduits, and means for driving said propeller wheels, valves controlling the respective condu ts, and

' conduit control means may be applied to means for adjusting said valves in unison either in a common direction or in oppo site directions.

2. In a ship, a pair of water conduits extending longitudinally through the ship,

propeller wheels in said conduits,means for driving said propeller wheels, a pair of slidable valve plates for controlling the flow of water through the said conduits, stems on the said valve plates, said stems overlapping one another and being formed with rack teeth on adjacent faces, a gear mesh ing with said rack teeth, and means for rotating said gear.

3. In a ship, a pair of water conduits extending longitudinally through the ship, propeller wheels in said conduits, means for drivin said )ro )eller wheels a air of slidable valve plates for controlling the fiow of water through the said conduits, stems on the said valve plates, said stems overlapping one another and being formed with rack teeth on adjacent faces, a gear mesh ing with said rack teeth, and means for rotating said gear, and means for shifting said gear, and with it the said valve plates, bodily in opposite directions.

4:. In a ship, a pair of water conduits extending longitudinally through the ship, propeller wheels in said conduits, means for driving said propeller wheels, a pair of slidable valve plates for controlling the flow of water through the said conduits, stems on the said valve plates, said stems overlapping one another and being formed with rack teeth on adjacent faces, a gear meshing with said rack teeth, and means for rotating said gear, comprising an electric motor, a slidable base plate on which said gear and motor are mounted, and means for shifting said base plate to cause the valves to be moved inversely in unison between open and closed positions.

5. In a ship, a pair of water conduits extending longitudinally through the ship, propeller wheels in said conduits, means for driving said propeller wheels, a pair of slidable valve plates for controlling the flow of water through the said conduits, stems on the said valve plates, said stems overlapping one another and being formed with rack teeth on adjacent faces, a gear meshing with said rack teeth, and means for rotating said gear, comprising an electric motor, a slidable base plate on which said gear and motor are mounted, and means for shifting said base plate to cause the valves to be moved inversely in unison between open and closed positions, including a threaded shaft fixed to said base plate, a gear-nut on said shaft, and means for rotating said gear-nut.

In testimony whereof I have aflixed my si ature.
